I uploaded a table with different string materials and their behavior to humidity. As you can see real gut has a very bad behavior. Nylgut or Silkgut has a very good one. My harp has this kind of strings for the lower strings and humidity changes was never a problem. If the sound is the same compared to real gut is discussed and can not be answered in general.
